Ki vette feleségül Poitoui Ágnes-t?

Poitoui Ágnes (ném.: Agnes von Poitou), (Poitou, 1025 –‎ Róma, 1077. december 14.) német királyné, bajor hercegnő és fiának, IV. Henriknek kiskorúsága ideje alatt a Német-római Birodalom régens császárnéja. V. Vilmosnak, Aquitánia és Poitou hercegének harmadik házasságából, Burgundi Ágnestől született leánya.

Henry III (German: Heinrich III, 28 October 1016 – 5 October 1056), called the Black (German: Heinrich der Schwarze) or the Pious, was Holy Roman Emperor from 1046 until his death in 1056. A member of the Salian dynasty, he was the eldest son of Conrad II and Gisela of Swabia.

Henry was raised by his father, who made him Duke of Bavaria in 1026, appointed him co-ruler in 1028 and bestowed him with the duchy of Swabia and the Kingdom of Burgundy ten years later in 1038. The emperor's death the following year ended a remarkably smooth and harmonious transition process towards Henry's sovereign rule, that was rather uncharacteristic for the Ottonian and Salian monarchs. Henry succeeded Conrad II as Duke of Carinthia and King of Italy and continued to pursue his father's political course on the basis of virtus et probitas (courage and honesty), which led to an unprecedented sacral exaltation of the kingship. In 1046 Henry ended the papal schism, was crowned Emperor by Pope Clement II, freed the Vatican from dependence on the Roman nobility and laid the foundation for its empire-wide authority. In the duchies, Henry enforced the sovereign royal right of disposition, thereby ensuring tighter control. In Lorraine, this led to years of conflict from which he emerged victorious. Another sphere of defiance formed in southern Germany from 1052 to 1055. Henry III died in 1056, aged only 39. Modern historians identify the final years of his reign as the beginning of a crisis in the Salian monarchy.
